Problems solved by technology

[0003] However, in the manufacturing process of thin film transistor liquid crystal display, it needs to go through a lot of equipment and process. During the manufacturing process, a large amount of static electricity will be accumulated on the glass substrate, resulting in electrostatic damage to large and long metal design traces, making the Its abnormal resistance value, open circuit or short circuit directly affects the yield rate of thin film transistor liquid crystal display products

Abstract

The invention provides an array substrate and a display panel. The array substrate comprises a first routing and a second routing, wherein the first routing comprises a main body part and a first projection part, and the first projection part is arranged on the side, close to the second wiring, of the main body part; the second wiring and the first projection part are oppositely arranged, and a first electrostatic protection electrode is arranged between the second wiring and the first projection part. The array substrate has the beneficial effects that, according to the array substrate and the display panel provided by the invention, the probability of damage by static electricity can be reduced, namely metal routings required in the panel cannot be influenced even if the damage by staticelectricity occurs, so that the product yield is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] In the TFT-LCD panel design, a large number of signals need to use metal wiring to connect to the peripheral drive circuit, so that the external drive signal and pulse timing signal are provided to the panel pixel area for display and drive. In the peripheral circuit traces, the most commonly used bulk and strip metal designs are used to reduce parasitic resistance and parasitic capacitance. [0003] However, in the manufacturing process of thin-film transistor liquid crystal displays, a lot of equipment and processes are required, and a large amount of static electricity will be accumulated on the glass substrate during the manufacturing process, resulting in electrostatic damage to large and long metal design traces, making the Abnormal resistance, open circuit or short circuit directly affect the y...
